This strongly correlated electron compound is known to exhibit a wide range of magnetic phases, including a recently uncovered biskyrmion phase. We observe a continuous transition from dendritic to stripe-like domains, followed by the formation of magnetic bubbles due to a field- and temperature dependent competition between in-plane and out-of-plane spin alignments. The magnetic bubble phase appears at comparable field- and temperature ranges","authors_text":"Alex de Lozanne, Dirk Wulferding, Han Woong Yeom, Ilkyu Yang, Jeehoon Kim, Jinho Yang, John B.
