Abstract
Shape of local hysteresis loops was studied by scanning probe microscopy using pulsed and in-field modes. Intermediate states on the loops measured in pulsed mode were revealed and explained by partial backswitching in the area under SPM tip. The obtained slope of the loops measured in the in-field mode was explained taking into account the interaction between two types of charges: induced in sample by switching voltage and in cantilever by modulation voltage. Dependence of loops slope on the position of the laser spot on the cantilever was found. Computer simulation was used for explanation of the observed data.
