Magnetization measurements in the mixed state of thick strips of carbon nanotubedoped MgB2 in crossed fields configurations are reported, together with numerical simulationsperformed with a geometry equivalent to the sample shape. The samples were subjected tomagnetic field components along mutually perpendicular directions, an oscillatory field in onedirection and a remanent magnetization in the perpendicular direction. The magnetic responsealong the oscillatory field and the magnetic relaxation perpendicular to it are observed andsimulated using the critical state theory. A remarkable quantitative agreement between theexperiment and the theory was obtained.
