Low power RF sputter deposition of oriented copper ferrite films

“…This is different from c-axis oriented hexagonal strontium ferrite films, which showed a large M R /M S value for the perpendicular loop and a low M R /M S for the parallel loop [1]. This shows that in the studied copper ferrite thin films, the shape of MH loop is not determined by magnetocrystalline anisotropy alone [6].…”

High perpendicular anisotropy in copper ferrite thin films

“…A high value of K1, a first-order magnetocrystalline anisotropy constant, has been reported, 17,18 e.g., K1=2 ϫ 10 6 erg/ cc and c-axis as the hard axis have been reported, taking into account the effect of twinning. 18 This corresponds to an anisotropy field of 2K1 / M s = 30 000 Oe.…”

Electrical, structural, magnetic and transport properties of Zn2BaFe16O27 doped with Cu2+

“…This ferrite when slowly cooled, starting from high temperatures, has a tetragonal deformed spinel structure below 630-660 K. The cubic form of CuFe 2 O 4 is obtained by heat treatment, that is quenching at high temperature [8]. The crystallographic phases differ in their magnetization and magneto-crystalline anisotropy [9]. The copper ferrite is commonly known to appear in two structural forms: a cubic one of spinel type (space group Gd3m) and a tetragonal one of space group I 4 [10].…”
