Directional growth and characterizations of orthorhombic HoMnO3 films
In this work, we synthesize the orthorhombic HoMnO3 films on the SrTiO3(1 0 0) and LaAlO3(1 1 0) substrates by pulsed laser deposition and study their crystalline and magnetic properties. The orthorhombic HoMnO3 film with its b-axis perpendicular to the film surface is grown on the LaAlO3(1 1 0) substrate, and shows clearly three magnetic transitions at 45, 10 and 7K, which are attributed to the magnetization process of incommensurate spin structure of Mn3+ for 10K
