Critical behaviour of the mean-field ferromagnet Cu1.02[Cr 1.77Ti0.24]Se4

Autor: Krok-Kowalski, Józef, Władarz, Grzegorz, Rduch, Paweł, Malicka, Ewa, Groń, Tadeusz, Guzik, Adam

Magnetization, M, and susceptibility, , measurements showed both strong lowering of magnetic moment in comparison with CuCr2Se4 matrix and zero- eld-cooling eld-cooling susceptibility splitting characteristic for the spin-glass behaviour. Isothermal

Magnetic coupling in CuCr2X4 (X = S, Se) spinel compounds obtained via substitution of the chromium ions by nonmagnetic Sb or Al ions

Autor: Krok-Kowalski, Józef, Malicka, Ewa, Władarz, Grzegorz, Groń, Tadeusz, Pawełczyk, Marian, Heimann, Jan, Pacyna, A. W.

Taking into account both the dc magnetic susceptibility and the magnetization measurements as well as the high-temperature expansion of the magnetic susceptibility procedure the hopping integrals and superexchange integrals for the first and second c

Influence of Cu, Ga and Au dopants and technology conditions on the magnetic interactions in HgCr2Se4 single crystals

Autor: Krok-Kowalski, Józef, Władarz, Grzegorz, Groń, Tadeusz, Duda, Henryk, Pacyna, A.W., Nikiforov, K., Rduch, Paweł

For single crystals HgCr2Se4 doped by nonmagnetic Cu+, Au2+ and Ga3+ ions and single crystals of HgCr2Se4 matrix growing in different synthesis conditions both the dc and ac magnetic susceptibility as well as the magnetization have been measured. As

Influence of substitution of the chromium ions by the nonmagnetic Sb and Al ions on the magnetization processes in CuCr2X4 (X = S, Se) spinels

Autor: Malicka, Ewa, Krok-Kowalski, Józef, Warczewski, Jerzy, Groń, Tadeusz, Duda, Henryk, Mydlarz, T., Pawełczyk, Marian, Pacyna, A. W., Rduch, Paweł, Władarz, Grzegorz

Both the dc and ac magnetic susceptibilities as well as magnetization measurements were used to study the influence of the dilution of the magnetic chromium subarray by nonmagnetic antimony and aluminium ions on the magnetization processes for four s
