We investigate the magnetic and electronic properties of Co/Zr multilayers with an emphasis on the interfacial effects. The saturation magnetization, coercivity, and uniaxial anisotropy depend significantly on Co thickness. Spin-wave resonance modes

We investigate the influence of Zn substitution on the magnetic and magnetocaloric properties in Cd1−xZnxCr2S4 (0 ≤ x ≤ 0.5). The Curie temperature was found to decrease from 87 to 21 ± 2 K when Zn content increases from 0 to 0.5, due to the i
