Anomalous behavior of the irreversible magnetization and time relaxation in YBa${}_2$Cu${}_3$O${}_7$ single crystals with splayed tracks

A. Silhanek, D. Niebieskikwiat, L. Civale +3

We have studied the angular dependence of the irreversible magnetization and its time relaxation in YBa${}_2$Cu${}_3$O${}_7$ single crystals with one or two families of columnar defects…
