“…For the case of ferromagnets, 16,19 the irreversible heating mainly occurs at the magnetization jump, namely when the domain reorientation occurs. For other magnetic materials, [7][8][9] it occurs at the first-order phase transition. Therefore, in the same way as for solid oxygen, the irreversible heating is considered to occur at the α-θ phase transition with magnetization jumps in the up and down sweeps.…”

“…The surplus energy can be obtained from µ 0 BdM, which mainly results in the heating as hysteresis loss. 20,21 In previous studies, [3][4][5][6][7][8][9][10][11][12][13][14][15] the authors were mainly interested in ∆T rev , which reveals isentropes in the magnetic fieldtemperature (B-T ) plane. The discontinuity in the isentropes indicates the phase boundary in the B-T phase diagram.…”

Dissipation inevitably occurs in first-order phase transitions, leading to irreversible heating. Conversely, the irreversible heating effect may indicate the occurrence of the first-order phase transition. We measured the temperature change at the magnetic-field-induced α-θ phase transition of solid oxygen. A significant temperature increase from 13 to 37 K, amounting to 700 J/mol, due to irreversible heating was observed at the first-order phase transition. We argue that the hysteresis loss of the magnetization curve and the dissipative structural transformation account for the irreversible heating. The measurement of irreversible heating can be utilized to detect the first-order phase transition in combination with an ultrahigh magnetic fields generated in a time of µs order.

“…[1,2] According to the report, since the phase transitions in high magnetic fields accompany structural phase transitions, a coupling of lattice degree of freedom is crucial to understand them. On the other hand, there are also other sequential transitions without structural change in low magnetic fields.…”

The magnetization curve in a frustrated two-leg spin-ladder system is theoretically studied using both analytical and numerical methods. This spin system is mapped onto a hard-core boson system, which is composed of bond-operators describing the triplon excitation. By the analytical method using the mean-field theory on the bond-operators, we show that cusp singularities emerge in the magnetization curve as a function of a magnetic field due to the strong frustration. This originates from a change of number of Fermi points in the bosonic dispersion relation with the applied field. It is analogous to Lifshitz transition. This singularity is clarified by numerical calculation with the density-matrix renormalization-group method. Our results will be useful to understand the magnetization process observed in the frustrated two-leg spin-ladder compound BiCu 2 PO 6 .

“…In contrast to the triplon BEC picture, the magnetization plateaus correspond to the valence bond solid and the solitonic lattice of the quasispinons. As a realistic material containing the F-2LSL, BiCu 2 PO 6 (BCPO) has been actively studied [15][16][17][18][19][20][21]. Casola et al have reported that a field-induced phase can be fit by a solitonic excitation of spinons originating from triplons instead of the triplon BEC picture [17], indicating a reconstruction of the quasiparticles and field-induced second-order phase transition.…”

The quantum phase transitions induced by a magnetic field are theoretically studied in a frustrated two-leg spin ladder. Using the density-matrix renormalization-group method, we find some magnetic phase transitions and plateaus in two different cases of strong and weak rung couplings. With the strong rung coupling, the three magnetization plateaus are found at 1/3, 1/2, and 2/3 due to the frustration. Those can be understood in terms of a quasispinon reconstructed from the singlet and the triplets of spins on a rung. The plateau at 1/2 corresponds to the valence bond solid of the quasispinons, while the plateaus at 1/3 and 2/3 can be associated with the array of quasispinons such as the soliton lattice. This is different from the usual BoseEinstein-condensation picture of triplons. Our results will be useful in understanding magnetization curves in BiCu 2 PO 6 .
