This approach is based on the Wolff clusterization technique [17] applied to a spin continuous system (described in detail in [22]). Here we present only a general idea based on modification of the so-called adding probability (adding a spin to a cluster) by an additional factor attributed to a local configuration (information) entropy of the selected system’s property (the magnetic anisotropy in our case). Finally, the adding probability takes the form (2) Pijadd=(1−exp(−EijcouplingkBT))exp(−αSiloc) where Eijcoupling is the direct exchange coupling energy between the spins attributed to nodes i and j, Siloc is the local configuration entropy of anisotropy (calculated in the defined sphere around the i-th node) and α is the factor responsible for strengthening and weakening of the entropy impact on the adding probability.","divisions":[{"label":"label","span":{"begin":671,"end":674}}],"tracks":[{"project":"TEST0","denotations":[{"id":"32825650-62-68-4109814","span":{"begin":275,"end":277},"obj":"[\"10040213\"]"}],"attributes":[{"subj":"32825650-62-68-4109814","pred":"source","obj":"TEST0"}]},{"project":"2_test","denotations":[{"id":"32825650-10040213-67240929","span":{"begin":275,"end":277},"obj":"10040213"}],"attributes":[{"subj":"32825650-10040213-67240929","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"TEST0","color":"#b8ec93","default":true},{"id":"2_test","color":"#ec93d2"}]}]}}
