Doping Dependence of the in-Plane Transition in CoSnS
Ivica Zivkovic, Mohamed A. Kassem, Yoshikazu Tabata +2
In CoSnS two transitions are observed, the main one to a ferromagnetic state at K and the second one, involving in-plane components at K. We fol…
Structural, Optical and Single-domain Magnetic Features of the Noncollinear Ferrimagnetic Nano-spinel Chromites ACrO (A = Ni, Co, and Mn)
Mohamed A. Kassem, Abdulaziz Abu El-Fadl, Ahmed M. Nashaat +1
Spinel chromites ACrO with inherent magnetic geometrical frustration usually exhibit a noncollinear ferrimagnetic ground state when A are magnetic ions, with possibly cryst…
Novel slow dynamics of phase transition in the partially ordered frustrated magnet DyRu2Si2
