In our study, we conduct magnetization and heat capacity measurements toinvestigate field-induced magnetic phase transitions within the newlysynthesized compound K2Ni2(SeO3)3, a spin-1 dimer system arranged on atriangular lattice. The Ni-Ni dimers exhibit a ferromagnetic intra-dimerinteraction, effectively behaving as an ensemble with a total spin of S=2. Incontrast, antiferromagnetic interactions manifest between these dimers on thetriangular lattice. The trigonal distortion of the NiO6 octahedra introduceseasy-axis magnetic anisotropy, accounting for the distinct magnetic phasediagrams observed when applying c-axis directional and in-plnae magneticfields. Notably, our investigation unveils a two-step phase transition with themagnetic field aligned with the c direction. We propose that the system at thefirst transition is from a paramagnetic state to an up-up-down state,characterized by the Z3 lattice-symmetry breaking. Subsequently, aBerezinskii-Kosterlitz-Thouless transition, involving the breaking of thec-axis spin-rotation symmetry, leads to the formation of the "Y state" at lowtemperatures. These findings yield valuable insights into the magnetic phasetransitions inherent to geometrically frustrated magnetic systems featuringdimer structures.
