Anisotropic field-induced melting of orbital ordered structure inPr0.6Ca0.4MnO3

Abstract: The magnetic field-dependent transport of Pr0.6Ca0.4MnO3 has been investigated to expose the field-induced melting of orbital ordering. The critical field and critical temperature for the melting of the orbital ordered state depend on the orientation of the applied magnetic field, seemingly independent of the nature of the magnetic phase. The crystalline c-axis is the hard axis of the field-induced melting, but in-plane anisotropy also exists, correlating with the anisotropic CE-type orbital-ordered structure.… Show more

“…With H rotating from the [001] to [010] direction, the effect of H on enhancing magnetic interactions decrease, which would weaken the tendency of sharp melting of COI phase. [ 9 ] The melting of CO phase would therefore take place gradually without a sharp down‐turn for H //[010] as observed. This also could explain the difference between θ = 5˚ and θ = 0˚ (upper of Figure 3c ): the strong SOC along θ = 0˚ direction tends to cause the collapse of COI phase in lower magnetic field with large jump of resistivity.…”

“…[ 35 , 36 ] The anisotropic orbital ordering might cause anisotropic melting of the insulator phase due to the intimate coupling between spin and orbital degree of freedom. [ 9 ] In the current work, the orbital ordering would induce anisotropic response of the SOC and double‐exchange interaction to the magnetic field. Along the direction with a high Mn‐O orbital integral, the magnetic field would increase the hopping probability of electron largely that could enhance the SOC and double‐exchange interaction along out‐of‐plane directions.…”
