DESCRIPTION:Speakers: Anna Maria Cucolo (University of Salerno)\nThe quant
 itative interpretation of MFM data is still a hot topic in the community o
 f scanning probe microscopists. Indeed\, the tip magnetic properties are a
  priori not known and quantitative MFM investigations may only be achieved
  through phenomenological pictures of the tip-sample interaction\, mainly 
 based on the so-called *point-probe approximation*. In such a model the ti
 p magnetization distribution is sketched as a single magnetic monopole and
  the measured MFM signal is used to determine the unknown magnetic charge 
 as well as its position within the real tip’s cone.\n\nHere we propose a
  magnetic characterization of the tip\, starting from MFM measurements on 
 *superconducting vortices*\, which appear in type-II superconductors in th
 e mixed state\, i.e. in magnetic fields  $H_{c1} \n\nhttps://indico.knu.ua
