TL;DR: In this paper, the influence of a magnetic field on the thermodynamic properties of Ca 2 - x Sr x RuO 4 in the intermediate metallic region with tilt and rotational distortions was studied.
Abstract: We have studied the influence of a magnetic field on the thermodynamic properties of Ca 2 - x Sr x RuO 4 in the intermediate metallic region with tilt and rotational distortions ( 0.2 ⩽ x ⩽ 0.5 ) . We find strong and anisotropic thermal expansion anomalies at low temperatures, which are suppressed and even reversed by a magnetic field. The metamagnetic transition of Ca 1.8 Sr 0.2 RuO 4 is accompanied by a large magnetostriction. Furthermore, we observe a strong magnetic-field dependence of c p / T and that can be explained by magnetic fluctuations.

TL;DR: In this paper, the magnetic properties of chill-cast Nd-Fe-Al rods have been studied as a function of Nd and Al concentrations, and it was shown that coercivity is dependent on the quenching rate, and high coercivity could only be obtained in alloys prepared after a relatively low quench rate.
Abstract: The magnetic properties of chill-cast Nd-Fe-Al rods have been studied as a function of Nd and Al concentrations. High coercivities were obtained in Nd 60 (Fe 3 Al) 40 , Nd 50 (Fe 3 Al) 50 and Nd 33 (Fe 10 Al) 67 alloys. The study on the melt-spun ribbons of these alloys has shown that coercivity is dependent on the quenching rate, and high coercivity could only be obtained in alloys prepared after a relatively low quenching rate. Several crystalline Nd-Fe-Al phases have been investigated in this work. A metastable tetragonal phase existed as nearly the single phase in Nd 33 (Fe y Al) 67 with y = 2-4. The tetragonal phase is antiferromagnetic with a Noel temperature of 260K. Metamagnetism and magnetoresistivity have been observed. The study on the annealed Nd 33 (FeAl) 67 alloy has shown that a hexagonal phase and an unknown were formed and these two Fe-containing phases, among which one is an antiferromagnetic with a Noel temperature of 280K and the another is ferromagnetic below 130-140 K.

TL;DR: Magnetization of UNi1−xRuxAl solid solutions was measured at 4.2 K on isotropic powder samples in pulsed magnetic fields up to 26 T as mentioned in this paper.
Abstract: Magnetization of UNi1−xRuxAl solid solutions was measured at 4.2 K on isotropic powder samples in pulsed magnetic fields up to 26 T. Antiferromagnetism of UNiAl is suppressed completely for x=0.15 as inferred from the loss of metamagnetic transition on the high-field magnetization curve. The compounds with 0.15
