Quantum depinning of the magnetic vortex core in micron-size permalloy disks
Ricardo Zarzuela, Saül Vélez, Joan Manel Hernandez +2
The vortex state, characterized by an in-plane closed flux domain structure and an out-of-plane magnetization at its centre (the vortex core), is one of the magnetic equilibria of…
Anisotropic magnetic deflagration in single crystals of Gd5Ge4
S. Vélez, J. M. Hernandez, A. García-Santiago +6
Experimental evidence of the anisotropy of the magnetic deflagration associated with the low-temperature first order antiferromagnetic (AFM) --> ferromagnetic (FM) phase-transition…
Magnetic field dependence of the quantum tunneling of normal-superconductor interfaces in a type-I Pb superconductor
Saül Vélez, Ricardo Zarzuela, Antoni García-Santiago +1
We report experimental evidence of the effect of an applied magnetic field on the non-thermal magnetic relaxation in a disk-shaped type-I lead superconductor. The time evolution of…
The role of temperature in the magnetic irreversibility of type-I Pb superconductors
Saül Vélez, Antoni García-Santiago, Joan Manel Hernandez +1
Evidence of how temperature takes part in the magnetic irreversibility in the intermediate state of a cylinder and various disks of pure type-I superconducting lead is presented. I…
