In this paper it is shown that the phase self inductance and resistance, both measured at a high frequency, of a permanent magnet (PM) motor with non-salient rotor vary slightly with the rotor position. The origin of these variations is deeply inve ...
We study from first principles the magnetism in graphene induced by single carbon atom defects. For two types of defects considered in our study, the hydrogen chemisorption defect and the vacancy defect, the magnetism due to the defect-induced extended sta ...
Magnetization, neutron diffraction, and antiferromagnetic resonance measurements were employed to investigate the magnetic ground state of Ni-5(TeO3)(4)Br-2 single crystal. Despite the layered topology of the Ni2+ sites, typical for frustrated antiferromag ...
Large single crystals of the new magnetic solid RbNa3Fe7(PO4)6 can be grown in a salt flux. Below the ferro-to-antiferromagnetic transition temp. of 6 K, the field (H) dependence of the magnetization (M) of an oriented crystal of exhibits equally spaced st ...
Heat and charge transport perpendicular to the plan in five Co/Cu stacks are studied using AC temperature gradients in the presence of a DC current. Large peaks in AC voltage response versus applied field are observed. This effect, measured only in reversi ...
We report specific-heat measurements at magnetic fields up to 20 T on the recently discovered superconductor SmFeAsO0.85F0.15. The B-T diagram of a polycrystalline SmFeAsO0.85F0.15 sample with T-c=46 K was investigated. The temperature dependence of B-c2 w ...
Periodic arrays of elongated cobalt islands exchange coupled to continuous Permalloy thin films were fabricated using silicon nitride stencil masks and the magnetic spin configurations during magnetization reversal were studied with photoemission electron ...
Magnetic anomalies observed by the Mars Global Surveyor mission are attributed to crustal remanence. SNC (Shergotty-Nakhla-Chassigny) meteorites are likely samples of the Martian crust and are amenable to mineralogical and magnetic measurements essential t ...
In this paper it is shown that the phase self inductance and resistance, both measured at a high frequency, of a permanent magnet (PM) motor with non-salient rotor vary slightly with the rotor position. The origin of these variations is deeply investigated ...

We present a microscopic theory for the phonon-driven decay of the magnetization fluctuations in a wide class of nanomagnets where the dominant energy is set by isotropic exchange and/or uniaxial anisotropy. Based on the Zwanzig-Mori projection formalism, ...
