Tunable Multiferroic Properties in Nanocomposite PbTiO 3 -CoFe 2 O 4 Epitaxial Thin Films
Makoto Murakami,Kao-Shuo Chang,M. A. Aronova,Cailu Lin,Ming H. Yu,J. Hattrick Simpers,Manfred Wuttig,Ichiro Takeuchi,Chen Gao,Bo Hu,Samuel E. Lofland,L.A. Knauss,Leonid A. Bendersky +12 more
TL;DR: In this paper, the synthesis of PbTiO3 and CoFe2O4 multiferroic nanocomposites and continuous tuning of their ferroelectric and magnetic properties as a function of the average composition on thin-film composition spreads was reported.
Journal ArticleDOI

TL;DR: In this paper, a Co doped rutile thin film was fabricated on α-Al2O3 (10-12) substrates by laser molecular beam epitaxy.
Journal ArticleDOI
Microstructure and phase control in Bi–Fe–O multiferroic nanocomposite thin films
Makoto Murakami,S. Fujino,S.-H. Lim,Lourdes Salamanca-Riba,Manfred Wuttig,Ichiro Takeuchi,Bindhu Varughese,H. Sugaya,T. Hasegawa,Samuel E. Lofland +9 more
TL;DR: In this article, a multiphase thin film growth in the Bi-Fe-O system was reported, where the dominant phase formed in the film continuously changes from ferroelectric BiFeO3 to a mixture of α-Fe2O3 and ferromagnetic γ-Fe 2O3.
Journal ArticleDOI
Role of diffused Co atoms in improving effective exchange coupling in Sm-Co/Fe spring magnets
Y. Choi,Y. Choi,J. S. Jiang,Yong Ding,Richard A. Rosenberg,John E. Pearson,S. D. Bader,A. Zambano,Makoto Murakami,Ichiro Takeuchi,Zhong Lin Wang,J. P. Liu +11 more
TL;DR: In this article, the magnetization reversal processes of constituent elements and layers were studied with an emphasis on the role of diffused Co atoms, where significant Co diffusion into the Fe layer was observed by means of electron microscopy.
Journal ArticleDOI
Structural control and combinatorial doping of titanium dioxide thin films by laser molecular beam epitaxy
Yuji Matsumoto,Makoto Murakami,T. Hasegawa,Tomoteru Fukumura,Masashi Kawasaki,Parhat Ahmet,Ken Nakajima,Toyohiro Chikyow,Hideomi Koinuma +8 more
TL;DR: In this paper, the rutile phase of the TiO2 thin film was grown on α-Al2O3(0.0.1) substrate, while the anatase phase was on SrTiO3 (0, 0.1), and LaAlO 3(0, 0. 1) substrate.
