The effect of hydrostatic pressure on antiferromagnetic ordering of Cr spins, magnetic compensation, and exotic spin switching in the single-crystal $\mathrm{GdCr}{\mathrm{O}}_{3}$ ferrimagnet is studied. The N\'eel temperature ${T}_{\mathrm{N}}=168\

An unusual exchange bias (EB) effect in single-crystalline $\mathrm{GdCr}{\mathrm{O}}_{3}$ compensated ferrimagnet (fM), composed of two antiferromagnetically coupled Gd and Cr sublattices, presenting two opposite ferromagnetic (FM) moments, is repor

Magnetic and structural properties of CaMn1– x Re x O3 (0.02 ≤ x ≤ 0.1) have been investigated. Substitution of Re5+ ion for the Mn4+ site of 3 generates Mn3+ ions according to the chemical formula CaMn1–2 x 4+Mn x 3+Re x 5+O3, accompanied by

Recent experiments showed magnetic moment reversal and pronounced exchange-bias (EB) effect in the vicinity of the compensation temperature ${T}_{\mathrm{comp}}$ of orthoferrites $R\mathrm{Fe}{\mathrm{O}}_{3}$ ($R=\mathrm{Nd}$, Sm, Er). Although diff

The exchange bias (EB) effect and an appearance of the Griffiths phase (GP) were found in half-doped cobaltite $\mathrm{G}{\mathrm{d}}_{0.5}\mathrm{S}{\mathrm{r}}_{0.5}\mathrm{Co}{\mathrm{O}}_{3\ensuremath{-}\ensuremath{\delta}}$ exhibiting a signifi

Magnetic properties of bulk polycrystalline Mn-doped SrRu 1− x Mn x O 3 perovskite, at doping range 0.2≤ x ≤0.3, were studied by both magnetization and ac-susceptibility measurements. It was found that the exchange bias (EB) effect emerges with

The exchange-bias (EB) effect with sign reversal was found in $\mathrm{LuF}{\mathrm{e}}_{0.5}\mathrm{C}{\mathrm{r}}_{0.5}{\mathrm{O}}_{3}$ ferrite-chromite, which is a weak ferrimagnet below ${T}_{\mathrm{N}}=265\phantom{\rule{0.16em}{0ex}}\mathrm{K}

The effect of hydrostatic pressure on complex magnetic phase diagram of $\mathrm{LuF}{\mathrm{e}}_{2}{\mathrm{O}}_{4}$ has been investigated by various magnetic measurements in the range of 0--12 kbar. The temperature of the ferrimagnetic (fM) transi
