The triangular S=3/2 antiferromagnetic alpha-phase MCr2O4 (M=Ca, Sr, Ba) family has received increasing attention for their low dimensional geometrically frustrated magnetism. For the first time, the single crystals of alpha-SrCr2O4 were successfully grown by the floating-zone method. The plate-like crystals are highly a-axis oriented with a 60 twinning structure in the bc plane. We also investigated the magnetic susceptibilities, specific heat and dielectric properties systematically. Our results confirm a long range magnetic ordering emerging in alpha-SrCr2O4 below about 43 K. These crystals are suitable for the future neutron scattering experiments and other in-depth physical measurements. (C) 2014 Elsevier By. All rights reserved,
