Correlated decay of triplet excitations in the shastry-sutherland compound SrCu2 (BO3)2
Zayed, M.E.; Ruegg, C.; Strassle, T.; Stuhr, U.; Roessli, B.; Ay, M.; Mesot, J.; Link, P.; Pomjakushina, E.; Stingaciu, M.; Conder, K.; Ronnow, H.M.... more authors ... less authors ( American Physical Society , 2014 , Article)The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu2(BO3)2 is studied by means of inelastic neutron scattering. The excitation amplitude rapidly decreases ... -
Temperature dependence of the pressure induced monoclinic distortion in the spin S=1/2 Shastry–Sutherland compound SrCu2(BO3)2
Zayed, M.E.; Ruegg, C.; Pomjakushina, E.; Stingaciu, M.; Conder, K.; Hanfland, M.; Merlini, M.; Ronnow, H.M.... more authors ... less authors ( Elsevier Ltd , 2014 , Article)We investigate the monoclinic distortion that occurs at 4.7 GPa at room temperature in the frustrated Shastry-Sutherland model quantum magnet SrCu 2(BO3)2 as a function of pressure and temperature by means of powder and ...
