TL;DR: In this paper, a simple single-phase material, a random close-packed ensemble of highly monodisperse bare maghemite (γ-Fe2O3) nanoparticles, is shown to exhibit ideal superspinglass behavior (mimicking that of model spin-glasses), namely, an unprecedentedly sharp onset of the absorption component of the ac susceptibility, narrow memory dips in the zero-field-cooled magnetization and a spin-glass characteristic field-dependence of the magnetic susceptibility.

TL;DR: In this paper, the fundamental question as to the relative importance of interparticle superexchange versus dipolar interaction between oxide magnetic particles in direct physical contact is addressed by examinin...

TL;DR: In this paper, the authors have fabricated polycrystalline Ni50-xFexMn40Sn10 (x = 0, 2, 4, 6, 8, 8) melt-spun ribbons, starting from the base alloy with x = 0 which is weakly magnetic in both austenitic and martensitic phases, and found that Fe and/or magnetic field reduce the MT temperature and Curie temperature of austenite phase, becoming closer to each other as the Fe-content increases, accompanied by an increase of the magnetic moment of aust

TL;DR: In this paper, a multistep superelastic behavior with up to a 12% strain was reported in a 〈001〉P-oriented Ni49Mn28Ga23 single crystal and the observed behavior was produced by intermartensitic transformations during the tensile stress-strain measurements at temperatures between −140 °C and +60 C.

TL;DR: The open Novamag database is described, which contains significant results of novel magnetic phases with high magnetocrystalline anisotropy obtained by three computational high-throughput screening approaches based on a crystal structure prediction method using an Adaptive Genetic Algorithm.
