DESCRIPTION:In recent years\, the realization of magnetic long-range order
  in atomically thin 2D materials has shown a big potential in spintronic a
 pplications in ultrathin magnets due to the possibility of manipulation of
  magnetism by external fields\, strain or proximity effects in van der Waa
 ls heterostructures. Specifically\, the family of metallic magnets FenGeTe
 2 (n=3\, 4\, 5) has attracted a huge attention due to their high Curie tem
 peratures and intriguing properties. In this talk\, I will review the stat
 us of this research field\, highlighting our own research by ab initio den
 sity functional theory\, calculations of interatomic exchange interaction 
 parameters and Monte Carlo simulations. I will discuss the dependence of s
 tacking sequence on magnetism in CrI3 multilayers and complex magnetism in
  2D FeS2. A particular emphasis will be given on the systematic study of t
 he electronic structure and magnetism of FenGeTe2 magnets along with some 
 critical discussions on the importance of electron correlation with the ai
 d of dynamical mean field theory\, spin-orbit coupling and effects of tran
 sition metal doping.\n \n[1] S. Ghosh\, S. Ershadrad\, V. Borisov\, B. San
