NdBaCo2O5 + δ, $$\delta \approx 0.5$$ , layered cobaltite is a metamagnet, which at a relatively low magnetic field transforms below T ~ 20 K from the antiferromagnetic phase to the mixed ferromagnetic state. Above T ~ 20 K, it is a mixture of excha

The nature of the training effect in exchange-biased compounds is studied. This effect consists in a decrease in the exchange bias field (HEB) during a cyclic change in the magnetic field. The electrical resistivity training effects in the GdBaCo2O5

A scheme is proposed to describe the spin state of the Co3+ ions in the layered TbBaCo2O5.5 cobaltite near the metal–insulator transition. The spin state of the Co3+ ions in the metallic phase corresponds to a mixture of the HS( $$t_{{2g}}^{4}$$ $$

The resistance of single-crystal La1.2Sr1.8Mn2(1 – z)O7 is studied experimentally and theoretically in the 75–300 K temperature range in magnetic fields varying in intensity from 0 to 90 kOe. The magnetoresistance is governed by spin-polaron and

We have analyzed the resistance of La1.2Sr1.8Mn2(1 – z)O7 single crystal in magnetic fields from 0 to 90 kOe in the ferromagnetic temperature range. The observed magnetoresistance of La1.2Sr1.8Mn2O7 is described based on the spin-polaron conduction

The nature of the training effect in exchange bias compounds, which consists in a decrease in the exchange bias field HEB under magnetic field cycling, is clarified. It is shown that the training effect in GdBaCo2O5 + δ cobaltite with δ ≈ 0.5 is

The resistance of a La1.2Sr1.8Mn2(1–z)O7 single crystal has been studied in magnetic fields from 0 to 90 kOe. The magnetoresistance at temperature T = 75 K, near which a colossal magnetoresistance maximum is observed, has been successfully describe

A new scheme interpreting the changes in the spin state of Co3+ ions in GdBaCo2O5.5 in the course of the metal–insulator transition is proposed. The transition occurs gradually within a wide (~100 K) temperature range. The changes in the spin state

It is established that excess oxygen content δ influences the exchange bias (EB) in layered GdBa-Co2O5 + δ cobaltite. The EB effect arises in p-type (δ > 0.5) cobaltite and disappears in n-type (δ < 0.5) cobaltite. The main parameters of EB in Gd
