Abstract: Abstract In this work, the evolution of magnetic ground state and exchange bias (EB) with Al substitution in Ni50Mn37Sb13-xAlx Heusler alloys was investigated in detail. Al doping reduces the cell volume, enhancing antiferromagnetic interactions between… read more here.

Abstract: Reentrant spin glasses are frustrated disordered ferromagnets developing vortex-like textures under an applied magnetic field. Our study of a Ni$_{0.81}$Mn$_{0.19}$ single crystal by small angle neutron scattering clarifies their internal structure and shows that these… read more here.
