At P = 0, the strong hysteretic nature of metal-insulator transition ͑MIT͒ and the abrupt decrease of c by several orders just below T C suggest that the FM transition is discontinuous in nature. The application of pressure strongly decreases c , shifts MIT to higher temperature at the rate of 19 K / GPa, and suppresses the hysteresis width. The nature of the FM phase transition would change from discontinuous to continuous at around P = 2.5 GPa.

Effect of magnetic field and pressure on charge-orbital ordering in Pr(Sr1−xCax)2Mn2O7 (x = 0.4 and 0.9) single crystals

“…As PSCMO4 sample is close to metalinsulator phase boundary, the effect of hydrostatic pressure on magnetic transition can be significant as in the case of other perovskite manganites with ferromagnetic ground state. [15][16][17][18][19][20][21][22][23][24] In conclusion, we have investigated the effect of hydrostatic pressure and magnetic field on magnetic, CO-OO, and structural transitions for Pr(Sr 1Àx Ca x ) 2 Mn 2 O 7 (x ¼ 0.4 and 0.9). At low field, both the systems are magnetically highly anisotropic but the anisotropy decreases systematically with the increase of H. For x ¼ 0.4 sample, CO-OO transition is insensitive to both H and P, while the antiferromagnetic transition shifts towards higher temperature with the increase of P. For x ¼ 0.9 sample, with the increase of P, though the high-temperature CO-OO transition does not get affected significantly, the low-temperature CO-OO transition decreases rapidly.…”

Cooling by adiabatic pressure application in La0.7Ca0.3MnO3 magnetocaloric effect material

“…Though the pressure dependence of magnetic properties has been studied in manganites [4][5][6][7][8][9][10][11][12], to the best of our knowledge this is the first report on the influence of pressure on magnetocaloric effect and on the barocaloric effect in this group of materials.…”

Structural, Dielectric and Thermal Investigations of Ni0.8Zn0.2Fe2O4 Fine Particles

“…The advancements in the micro-and nano-electronics have demanded materials with high performance at small size, which is very well fulfilled by the soft ferrites as these are very much reliable at high frequencies and consume relatively little power. [1][2][3] Different methods of preparation of small size ferrites exists. 4 5 The size of the ferrites is very dependent on the preparation technique used for the synthesis.…”
