Spiral magnetic structure in spin-5/2 frustrated trimerized chains in SrMn3P4O14

Masashi Hase, Vladimir Yu. Pomjakushin, Lukas Keller +7

We study a spin-5/2 antiferromagnetic trimerized chain substance SrMn3P4O14 using neutron powder diffraction experiments. The coplanar spiral magnetic structure appears below T_N1…

Magnetic excitations in the spin-5/2 antiferromagnetic trimer substance SrMn3P4O14

Masashi Hase, Masaaki Matsuda, Koji Kaneko +7

A quantum-mechanical 1/3 magnetization plateau and magnetic long-range order appear in the large-spin (5/2) substance SrMn3P4O14. Magnetization results of SrMn3P4O14 can be explain…

Coexistence of a nearly spin-singlet state and antiferromagnetic long-range order in quantum spin system Cu $_{2}$ CdB $_{2}$ O $_{6}$

Masashi Hase, Masanori Kohno, Hideaki Kitazawa +5

A 1/2 magnetization plateau in magnetic fields above 23 T and antiferromagnetic (AF) long-range order (AFLRO) in low fields were found in Cu $_{2}$ CdB $_{2}$ O $_{6}$ . Experimental results a…

Magnetism of Cu_6 Ge_6 O_{18}-x H_2 O (x = 0 ~ 6), a compound of the one-dimensional Heisenberg $S = 1/2$ model with competing antiferromagnetic interactions

Masashi Hase, Kiyoshi Ozawa, Norio Shinya

We measured the magnetic susceptibilities of Cu $_{6}$ Ge $_{6}$ O $_{18}$ -xH $_{2}$ O ( $x = 0 \sim 6$ ). Susceptibility above the antiferromagnetic (AF) transition temperature ( $T_{N}$ ) agr…
