$^{89}$Y nuclear spin-lattice relaxation in SrY$_2$O$_4$:Ho$^{3+}$ single crystals
Measurements of 89Y nuclear spin-lattice relaxation in SrY2O4:Ho3+ crystals for the magnetic field B parallel to the crystal c axis show that 89Y at T < 20 K relaxes due to fluctuating magnetic field created only by Ho13+ transitions between the ground and the first excited Zeeman sublevels of the 5I8 multiplet.
