The phase diagram of the magnetocaloric MnxFe2−xP1−ySiy quaternary compounds was established by characterising the structure, thermal and magnetic properties in a wide range of compositions (for a Mn fraction of 0.3 ≤ x < 2.0 and a Si fraction of 0.33 ≤ y ≤ 0.60). The highest ferromagnetic transition temperature (Mn0.3Fe1.7P0.6Si0.4, TC = 470 K) is found for low Mn and high Si contents, while the lowest is found for low Fe and Si contents (Mn1.7Fe0.3P0.6Si0.4, TC = 65 K) in the MnxFe2−xP1−ySiy phase diagram. The largest hysteresis (91 K) was observed for a metal ratio close to Fe:Mn = 1:1 (corresponding to x = 0.9, y = 0.33). Both Mn-rich with high Si and Fe-rich samples with low Si concentration were found to show low hysteresis (≤2 K). These compositions with a low hysteresis form promising candidate materials for thermomagnetic applications.

Magnetic Phases

The magnetic susceptibility measurements have been made on antiferromagnetic compounds Mn1–xFexSn2 and the magnetic phase diagram was illustrated. The high temperature magnetic phases I and III, major phases, were analyzed on the basis of molecular field theory and explained the change of magnetic structure I⇌III occured at x≈0.8.

Complete Investigation

In this paper, a complete investigation of the magnetic properties of the Hubbard model on the AB2 chain is presented. We evaluate the magnetic phase diagram as a function of the electron–electron interaction and band filling by using the Green's function method within the Hartree–Fock approximation. Our results are in agreement with Lieb's theorem and the system shows ferromagnetic, ferrimagnetic, and paramagnetic phases.

Thermal Variation

Thermal variation of the magnetic susceptibility for Ti-Co solid solutions is reported. Cobalt, by alloying acts on the transition Néel temperature giving rise to a complicated magnetic phase diagram. The change of the Fermi level is the main mechanism in the critical temperature, T N , shift.

The magnetic properties of a diluted ferrimagnetic spinels system CoFe2–2xCr2xO4 are studied using the high-temperature series expansions method in the range 0 ≤ x ≤ 1. The inter-sublattice exchange interactions (JCo Cr or JCo–Fe) are calculated using the probability law. The high-temperature series expansions, together with the Padé-approximants method, are applied to the spinels systems CoFe2–2xCr2xO4 to determine the magnetic phase diagram, i.e., TC versus dilution x. The critical exponent associated with the magnetic susceptibility (γ) is deduced. PACS Nos.: 75.30.Et; 75.40.Cx; 74.25.Ha, 75.30.Cr
