Magnetic anisotropy of the spin tetramer system SeCuO3 studied by torque magnetometry and ESR spectroscopy

We present an experimental study of macroscopic and microscopic magnetic anisotropy of a spin tetramer system SeCuO3 using torque magnetometry and ESR spectroscopy. Large rotation of macroscopic magnetic axes with temperature observed from torque magnetome ...

Magnetic, structural, and electronic properties of the multiferroic compound FeTe2O5Br with geometrical frustration

Helmuth Berger

We report electron spin resonance (ESR), Raman scattering, and interband absorption measurements of the multiferroic FeTe2O5Br with two successive magnetic transitions at T-N1 = 11.0 K and T-N2 = 10.5 K. ESR measurements show all characteristics of a low-d ...

Magnetization reversal mechanism of ramified and compact Co islands on Pt(111)

Harald Brune, Stefano Rusponi, Donat Fabian Natterer, Anne Lehnert, Alberto Cavallin, Géraud Moulas

We report on the magnetization reversal mechanism of Co islands on Pt(111) as a function of their size and shape. We measure the zero-field susceptibility chi(T) and low-temperature magnetization curves M(H) with in situ magneto-optical Kerr effect. Togeth ...

Cluster-size dependent internal dynamics and magnetic anisotropy of Ho ions in HoM2N@C-80 and Ho2MN@C-80 families (M = Sc, Lu, Y)

Yi Zhang, Jan Gui-Hyon Dreiser

The paramagnetic NMR study of HoM2N@C-80-I-h and Ho2MN@C-80-I-h nitride cluster fullerenes (M = Sc, Lu, Y) reveals strong dependence of Ho-induced paramagnetic shifts (delta(para)) in C-13 NMR spectra on the size of the diamagnetic metal in the cluster. In ...

Sound Isolation and Giant Linear Nonreciprocity in a Compact Acoustic Circulator

Romain Christophe Rémy Fleury

Acoustic isolation and nonreciprocal sound transmission are highly desirable in many practical scenarios. They may be realized with nonlinear or magneto-acoustic effects, but only at the price of high power levels and impractically large volumes. In contra ...

Inkjet printed superparamagnetic polymer composite hemispheres with programmed magnetic anisotropy

Jürgen Brugger, Massimo Mastrangeli, Christofer Hierold, Victor Javier Cadarso Busto, Rosario Maurizio Gullo, Loïc Jacot-Descombes, Berna Ayse Özkale Edelmann

We present the fabrication and characterization of large arrays of inkjet-printed superparamagnetic polymer composite (SPMPC) hemispherical microstructures. SPMPCs are appealing for applications in microsystems and nanorobotics due to the added functionali ...

A Uranium-Based UO2+-Mn2+ Single-Chain Magnet Assembled trough Cation-Cation Interactions

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Single-chain magnets (SCMs) are materials composed of magnetically isolated one-dimensional (1D) units exhibiting slow relaxation of magnetization. The occurrence of SCM behavior requires the fulfillment of stringent conditions for exchange and anisotropy ...

Magnetoelastic Clock System for Nanomagnet Logic

Mariagrazia Graziano, Davide Balma

In recent years, magnetic-based technologies, like nanomagnet logic (NML), are gaining increasing interest as possible substitutes of CMOS transistors. The possibility to mix logic and memory in the same device, coupled with a potential low power consumpti ...

The Metallofullerene Field-Induced Single-Ion Magnet HoSc2N@C-80

Jan Gui-Hyon Dreiser

The low-temperature magnetic properties of the endohedral metallofullerene HoSc2N@C-80 have been studied by superconducting quantum interference device (SQUID) magnetometry. Alternating current (ac) susceptibility measurements reveal that this molecule exh ...

Gutzwiller electronic structure calculations applied to transition metals: Kinetic energy gain with ferromagnetic order in bcc Fe

Giovanni Borghi

The Gutzwiller projector technique has long been known as a method to include correlations in electronic structure calculations. We describe a model implementation for a Gutzwiller + LDA calculation in a localized-orbital restricted basis framework, emphas ...
